Of course, letting guests and friends be in charge of sacrificial offerings is just good manners.
I think the key is that the monument must be a) historically significant and a testament to human design and b) interactive with the surrounding space. Hence, the ban on single pieces of architecture. Your 1/16 size Eiffel Tower does not impress me! Other contenders: Mesopotamian ziggurats, Egyptian pyramids (ugh, this is so CLICHED though; I’d prefer to see the Great Temple of Amun, Karnak), Great Stupa of Sanchi.
How didn’t I think of this?! Mecca! I want a replica of the entire Mecca in my best friend’s front yard. And we are in Ramadan + Ground Zero Mosque hysteria, just imagine the neighborhood impact of such a construction. It would be like a Disneyland for fanatics!
For the past decade and a half I have been making all my content available for free (and never behind a paywall) as an ongoing practice of ephemeral publishing. This site is no exception. If you wish to help offset my labor costs, you can donate on Paypal or you can subscribe to Patreon where I will not be putting my posts behind a lock but you'd be helping me continue making this work available for everyone. Thank you. Follow me on Twitter for new post updates.
